HPC in the building construction sector

Abstract: In the context of the HIPERCOSME project (1) (ESPRIT project 20059), the Universidad Politecnica de Valencia (UPV) in collaboration with Spanish partners, developed a new High Performance Computing (HPC) demonstrator to calculate Reinforced Concrete Building Structures. Starting from a sequential software package, the objective of that project was to develop a portable parallel software package, able to cope with large scale problems and more realistic models (more information could be obtained in http://wwwcopa.dsic.upv.es/copa_eng.html). The performance of the prototype was analysed by means of a test battery composed of 4 real buildings. The performance of the prototype was compared to that of the original sequential package, showing that the former was from 20 up to 60 times faster than the latter. Besides, since a trial and error process must be carried out, the best and cheapest structural solution can be obtained. This leads to a reduction of the cost of the constructive elements and an increase in safety. On the other hand, and as a consequence of the code performance, a 3D approach to the problem of computing the building structure can be performed. Hardware and software requirements for this prototype are very common.The parallel platform can be a cluster of Ethernet linked PC's running under an easily available operating system such as LINUX (public domain) and the PVM passing message environment (public domain also). Moreover, the application is portable and can be run on other computers and parallel systems. Thus, in the context of the project, five Workshops were organised to promote the results in the European regions where the project partners belonged to. In these Workshops, Demonstration Actions were carried out with the presence of different small and medium size construction enterprises of each region. Co-operation among the partners led to contacts with new construction companies interested in the HPCN framework. As a consequence, six Assessment Studies were developed with European construction companies from Spain, Portugal, France and Greece, in order to understand the needs of the European market. UPV is the Valencian Community node of HIPERTTN. This technological Transfer Node is part of the METIER action in the HPCN PST activities of the IV ESPRIT Programme. TTN's try to stimulate the technology transfer and dissemination of the results of the HPCN projects in Europe. As a consequence, a Construction Sector Group has been recently created in this TTN Network. In the full paper, we will describe the technical work developed in the project, both from the point of view of the computational tools and the experience of transference of technology to the Construction Sector.

An expertext system for building standards

Abstract: The paper describes work on a current collaborative research project involving UK Universities and the Scottish Office's Building Directorate. Previous work by the Directorate had identified limitations in a conventional expert systems approach to the development and management of building Standards information. Work in the current project seeks to overcome these limitations by combining representational paradigms. In particular, a system is being designed and implemented which is based on and seeks to extend the concept of Headed Record Expertext (Diaper 90) in which formalised information can be attached, where appropriate, to nodes in a hypertext version of the Standards. The systemalso handles navigation rules and provides intelligent guidance for the reader through the hyperdocument. The underlying node/arc representational structure is also intended to support the capture of argumentation material generated during the development, maintenance and use ofStandardsinformation.

Knowledge communication in the building industry - the knowledge node concept

Abstract: In the paper are given fundamental support to high level structuring and modelling of the building process. The concept of a knowledge node is explained and demonstrated in ongoing research projects together with industry. The enabling technologies accounted for are rich user interfaces in the form of multimedia, the World Wide Web, relational databases, and object-oriented languages as Java. The main conclusions from research projects combining a holistic visionary approach and practical implementations are that the described knowledge nodes with underlying general models act well as both distributed knowledge containers and knowledge communication tools both during the design of the node itself and its later targeted use.

Experiences from developing a buildingmaintenance knowledge node.

Abstract: The paper describes how technical building maintenance in the future can be effectivelycommunicated using Internet services. The research and development is done togetherwith the potential end users of the system (9 large building operations and maintenancefirms in Sweden). The national Swedish SERFIN , Maintenance ExperienceCommunication on Internet, project is described together with the philosophy behind thesystem, underlying models, and enabling technologies. The system under development is aknowledge node on the Internet where users independent of room and time can search forquality-marked information ,place questions and get answers back. The system alsocaptures knowledge within the area. The development work is supported by a workingarea and the in-house demonstrator development method. Both system and working areareside on the Internet. The latter are slowly transformed to an O&M area which supportsall the processes for knowledge handling and content quality assurance. Experiences andlessons learned as well as underlying system functionality and structure are reported.

Dynamic information system for modeling processes

Abstract: DINAMO is a dynamic Information System for Modeling of Design Processes. It is intended for use along with product models, data management systems and existing applications. In DINAMO a programming user can define processes. These processes are represented by graphs. The graphs are characterized by nodes and relations between nodes. Each node in a graph represents a task, and each relation can be restricted to conditions. So the way in which a process is actually been performed, that is the actual path to be evaluated through the graph, can depend on certain conditions. Processes and functions (= software modules) are available to the user as tasks. A consuming user can activate tasks; the DINAMO system regulates the dispatch of the tasks, conform the process and function definitions. Tasks are collected on sheets; sheets are collected in a task box. A task box can be regarded as a certain environment, determined by the programming user. A consuming user can choose between the environments which are available at that moment. With the DINAMO system software and process definitions can be re-used in a simple way.

Low-Cost Fleet Management Solutions in the Framework of Emerging Markets

Abstract: Implementation of ITS solutions in the emerging market of Egypt is at an early stage, yet has made significant progress. In the framework of PHAROS project, low-cost smart solutions have been developed for fleet managers to facilitate efficient route choices and eco-driving that minimize fuel consumption and carbon emissions. These solutions were integrated in an existing fleet management system. This paper presents the theoretical and practical formulation of the rescheduling component added to the already existing fleet management system. The rescheduling component is based on the development of an eco-path that considers the "cost" between two consecutive nodes. By the term "cost", more parameters such as path length, travel time, operating costs, energy consumption required for each route, are taken into account. Based on the above decision-routing parameters, through the use of a routing algorithm, the optimal path between the origin and the destination node is proposed.

Agents for Multi-User Virtual Environment (MUVE)

Abstract: Virtual user simulation has been used to simulate and predict the “average” user’s response to built environments. However, autonomous agents are seldom used in gaming environments. This is probably to ensure control over the game narrative. Also, the complexity in defining behavioural patterns tailored for the storyboard and the computing resources required make it difficult to incorporate autonomous agents in game environments. In this paper, we address the implementation of autonomous agents in a multi-user virtual environment designed as a game. Instead of the traditionally-used goals and behavioural rules to govern the behaviours of the agents, we used another mechanism, the switch-nodes. Switch-nodes are location-based triggers to control the behaviours of the agents. The nodes could trigger an action, a series of actions, an animation or a mixture of actions and animations. However, as the node system does not prevent conflicts or unreasonable behaviour in the environment, we experienced some challenges even for a narrow range of behavioural needs. Though so, with proper adjustments, careful planning and some creativity, we are able to achieve a “naturally appealing” behavioural pattern without negatively affecting the performance of the overall gaming environment.

PDI tools in the combine project

Abstract: Results from the COMBINE project (Computer Models for the Building Industry in Europe) are presented. This EU-funded project, now in it‘s second phase, deals with the development of integrated building design systems. COMBINE has concentrated on providing efficient data exchange between a number of “design nodes” in a network, each node being identified as an actor at a workstation in a LAN connected design team. The paper deals with the way data exchange facilities are delivered to the project in the form of a customizable interface kit.
